I was coming on here to post this exact same question. While at my MIL's house, some of my white cotton undies, white cotton w/flowers long johns, and several white socks somehow became light blue. None of the other things were stained. This never happens when I do laundry (I'm almost obsessively complusively anal), so I'm really not used to it. I did have one experience in college when one of my house mates had used the washing machine to dye something red and did not run the machine afterwards. Then, I took them out and ran the machine a couple of times to clean it and then soaked them in the machine in borax and washed them a few times after that and they were still pink tinged. It still took a couple of months to get them back to white again. This isn't very much, so I'm worried about washing them with my other whites. I don't want them to tinge my other whites. But I would think they would just stay dingy if I wash them with darks. It could be months before I could put them outside to get back to white by the sun, which is another thought of mine. Maybe I should do like you and get a bucket of warm water to soak them in. Since I live in France, I don't have oxyclean, so I'll have to use borax instead. Guess I need to put the bucket someplace high so that DS will not get into it.
